A nurse is educating a client about the inheritance pattern of cystic fibrosis (CF). What information should the nurse provide regarding the likelihood of a child developing CF if both parents are carriers?

"If both parents are carriers, there is a 50% chance that their child will have CF."

"If both parents are carriers, their child is guaranteed to have CF."

"If both parents are carriers, their child will be a carrier but will not have CF."

"If both parents are carriers, their child will have a 25% chance of having CF."

Answer and Explanation

The Correct Answer is D

A) Incorrect. If both parents are carriers, their child's risk of having CF is 25%, not 50%.

B) Incorrect. While the risk is increased, having two carrier parents does not guarantee that a child will have CF.

C) Incorrect. If both parents are carriers, their child can inherit two normal genes (no CF), one normal and one CF gene (carrier status), or two CF genes (CF).

D) Correct. When both parents are carriers, there is a 25% chance that their child will inherit two CF genes and have CF, a 50% chance of being a carrier, and a 25% chance of inheriting two normal genes (no CF).

Correct Answer is C

Explanation

A) Incorrect. CF occurs at a similar frequency in both males and females.

B) Incorrect. CF is not significantly associated with any specific ethnicity, and the risk is not influenced by being of African descent.

C) Correct. A family history of CF increases the risk because CF is an autosomal recessive genetic disorder, and having affected family members increases the likelihood of carrying CF gene mutations.

D) Incorrect. While CF can affect individuals from any ethnicity, it is primarily a genetic disorder, and family history plays a crucial role in the risk of inheritance.

A. Postural drainage and chest percussion B. Administering bronchodilators as needed C. Providing oxygen therapy around the clock D. Encouraging deep breathing exercises only during illness

Correct Answer is A

Explanation

A) Correct. Postural drainage and chest percussion help mobilize and remove thick, sticky mucus from the airways, which is crucial in managing CF.

B) Incorrect. While bronchodilators may be used, they are not the primary therapy for managing CF. Airway clearance techniques like postural drainage are more important.

C) Incorrect. Oxygen therapy should be administered as needed, but it is not required around the clock for all CF patients.

D) Incorrect. Deep breathing exercises should be encouraged regularly, not just during illness, to maintain airway clearance and lung function.
